Died after coming though end gate way

What Happened:

I know there are similar reports of this but this one was differant. so basically i went though the first endgate way no problem get my stuff from the end city but when i through my ender pearl though the end gateway i go through and spawn 4 blocks under the gateway and fall to into the void

Steps to recreate:

1. load up a 19w39a world 

2. go into the end

3. kill the dragon

4. go through the end gateway

5. unload the chunk the exit gateway was

6. re-enter the chunks

7. go through the gateway
